Robinhood doesn't even have the decency to interview you with their own employees. First you need to interview with a 3rd party company named Karat, and you're asked random questions that have nothing to do with the job you're applying for.
The interview starts with some trivia question about random things like load balancing and such. Those aren't too bad, but not really related to the position.
The coding party wasn't too bad either. I wrote a mostly working solution that worked for most cases, but it had a problem somewhere that failed in one case. I attempted to fix it but ran out of time, and that was enough for them to say no.
I would normally be upset, but if they really won't hire someone due to a small bug that would have been found in real life using an IDE, then imagine how stressful it must be to work there. Are they expecting their developers to write perfect code in one go without debugging? I say I got lucky by not getting stuck there.
